ST Glass 6-circuit fuse block with negative bus and cover

This Blue Sea Systems fuse block is specifically designed to accept ST type glass fuses.

The BLUE SEA ST Glass 5015-BSS fuse block has six independent circuits for protecting your equipment.

A negative bus is a common connection bar integrated into the block that centralizes all return currents (grounds) from the different circuits. Its role is to simplify wiring by reducing the number of individual ground connections required, resulting in a cleaner and more organized installation.

Yes, a cover is included with the 5015-BSS fuse block. It is designed to protect the fuses and connections.

The main difference lies in the type of compatible fuses. The 5015-BSS model is specifically designed for glass-type ST fuses. In contrast, ATO/ATC blocks are made for blade-type fuses, which are more common in modern installations and often provide a visual status indication.

Yes, this fuse block is an electrical distribution solution specifically designed for marine applications, as stated by the manufacturer Blue Sea Systems.

Using a centralized fuse block offers several advantages:

Cleaner wiring organization.Effective protection for all electrical circuits.Simplified diagnosis and fuse replacement.Reduction in the number of individual wiring runs, especially with the integrated negative bus.

The exact dimensions of the 5015-BSS fuse block are:

Width: 88.9 mm (3.50 in)Length: 126.0 mm (4.96 in)Height: 31.8 mm (1.25 in)

No, fuses are not included with the 5015-BSS fuse block. They must be purchased separately based on your circuit requirements.

The supplied cover protects the fuses and electrical connections from splashes, dust, and accidental contact, thereby contributing to increased installation safety.

The included cover protects the fuses and connections from splashes. However, the specific waterproof rating of the block itself, beyond this cover protection, is not specified in the available information.

No, this fuse block, designed for ST-type glass fuses, does not include a built-in visual indicator (such as an LED) to signal a blown fuse. The fuse status must be checked visually or with a tester.

Connections for individual loads on this fuse block are made using #8 screws.

The main power source wiring (current input) is secured with #10 studs, providing a reliable connection.

The fuse block mounting holes are designed for #10 screws, ensuring a stable and robust attachment to the mounting surface.

The integrated negative bus greatly simplifies wiring by centralizing all current return (ground) connections at a single point. This reduces the number of individual cables to manage and allows for a neater, more efficient installation.

Yes, thanks to its compact dimensions (88.9mm width, 126.0mm length, and 31.8mm height), this fuse block is designed to facilitate installation even in confined spaces aboard your vessel.

Yes, to access the circuit connections and the negative bus for wiring, it is necessary to remove the fuse block cover.

This fuse block is ideal for protecting and distributing power to various equipment in marine applications. It is particularly suited to installations where the use of glass-type ST fuses is required, especially for maintaining existing equipment or specific applications needing this format.

No, this fuse block is specifically designed to accept ST-type glass fuses. ATO/ATC fuses have a different physical format and are not compatible with this model's fuse holders.
